The return of curbside compost collection resumes on Monday

The weekly curbside collection of compostable material in the city of Ann Arbor resumes Monday, April 5, 2021, on regular collection days. Compost collection routes run through Friday, Dec. 10, 2021. Residents can take advantage of this service by using optional compost carts and paper yard bags to dispose of materials appropriate for those containers and by bundling larger branches/brush and placing at the curb.

Paper yard bags may be used for yard trimmings such as leaves, weeds and other vegetation. Heavy bags can be difficult to service at times and also pose a greater injury and health risk to staff. If you must use paper yard bags, please don’t overload them. If you can’t lift it comfortably, neither can city staff.

Bundled brush or tree limbs, four feet or less, tied with natural twine in bundles up to 18 inches in diameter, can be left at the curb for pickup. Individual tree limbs must be less than 6 inches in diameter.
